Preheat your oven to 350°F (175°C) and grease a 9-inch pie dish with butter or olive oil.

In a skillet, melt 2 tablespoons of butter over medium heat. Add 1 cup chopped onion and cook until soft, about 5 minutes. Stir in 1 clove minced garlic.

Add 2 cups of corn kernels and sauté for 2-3 minutes. Remove from heat and cool slightly.

In a mixing bowl, whisk together 3 eggs, 1 cup of milk, and a pinch of salt and pepper.

Fold the corn mixture into the egg mixture along with 1 cup of shredded cheddar cheese.

Pour the filling into the pie dish and add a crust if desired.

Bake in the preheated oven for 35-40 minutes or until set and golden brown.

Let cool for about 10 minutes before slicing and serving.
